Foreword Th
16、is European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document defines the requirements of radio terminal and radio-relay equipment and associated interfaces. The present document is part 5 of a multi-part deliv
17、erable covering the Point-to-multipoint equipment; Point-to-multipoint digital radio systems in frequency bands in the range 24,25 GHz to 29,5 GHz using different access methods, as identified below: Part 1 : “Basic parameters“; Part 2: Part 3 : Part 4: Part 5: “Frequency Division Multiple Access (F
18、DMA) methods“; “Time Division Multiple Access (TDMA) methods“; “Direct Sequence Code Division Multiple Access (DS-CDMA) methods“; “Multi-Carrier Time Division Multiple Access (MC-TDMA) methods“. Parts 2 to 5 are intended to be used in conjunction with part 1, describing the basic parameters common t
19、o all access methods. A basic description of the different access methods and a comparison among them are provided in TR 101 274 2. The former title of the present document was: “Transmission and Multiplexing (TM); Digital Radio Relay Systems (DRRS); Point-to-multipoint DRRS in frequency bands in th

22、s common to all access methods. The present document specifies the minimum requirements for system parameters of Multi-Carrier Time Division Multiple Access (TDMA) Point-to-Multipoint (P-MP) Radio Systems in the terrestrial fixed services operating in the band 24,5 GHz to 29,5 GHz (see CEPT/ERC Reco
23、mmendation T/R 13-02 3). Only sections specific to TDMA are described in respect to the clauses stated in EN 301 213-1 i. Multi-Carrier Time Division Multiple Access (MC-TDMA) is an alternative to TDMA, FDMA and CDMA covered in other parts of the present document. In MC-TDMA Point to Multipoint (P-M
24、P) systems, a central station broadcasts information to terminal stations in a continuous Time Division Multiplex (TDM) or in a burst TDMA mode. The CRS andor TS may transmit one or more sub-carriers at various frequencies, bandwidths, modulation and power levels, however the normative requirements
25、relating to channel bandwidths and spectrum masks must be met. The Terminal stations transmit in TDMA mode. The users may have access to the spectrum by sharing it through time multiplexing. The present document is a new draft which contains: Introduction of a Multi-Carrier TDMA system, where a sing
26、le transmitter can transmit more than one sub - carrier. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication andor edition number or version
27、number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. il ETSI EN 301 213-1 : “Fixed Radio Systems; Point-to-multipoint equipment; Point-to-multipoint digital radio systems in frequency bands in the range 24,25

32、 of a transmitter working in burst mode the gross bit rate is the instantaneous maximum transmission bit rate during the burst. The gross bit rate has a unique relationship to the symbol rate through the implemented modulation format. multi-carrier: system where more than one modulated sub-carrier i

Regulatory bodies may choose appropriate parts of the above mentioned frequency bands for the application for Point-to-Multipoint systems. 4.2.2 Channel
36、arrangements The system shall meet at least one or more of the channel arrangements listed in table 1. Table 1: Channel arrangement 112 MHz I 256 Mbis 384 Mbis ETSI 8 ETSI EN 301 213-5V1.1.1 (2001-10) NOTE 1 : The minimum transmission bit rate is defied as the gross bit rate of the multi-carrier sys
37、tem assumed as sum of all sub-carriers gross bit rate. The sum of all upstream sub-carriers transmission bit rates for a fully equipped system shall meet the requirements for the system type declared by the manufacturer as per table 1. Where a different aggregate gross bit rate applies in each direc
38、tion, the system type declared shall indicate this by giving the system type for the downstream followed by a hyphen and then the system type for the upstream. For example, a system conforming to type C in the downstream direction and type A in the upstream direction should be declared as a type C-A
39、. Where the system type differs for upstream and downstream, the system shall meet all requirements for the declared system type for each direction. NOTE 2: Systems may offer a combination of Type A, Type B, and Type C, provided that such a system, when operating in mixed mode, complies with the mos
40、t stringent spectral mask for the types offered. A mix mode could consist of a system that operates with different system type on a per sub-carrier or time-slot basis or both. NOTE 3: System Type A is primarily covering 4 states or equivalent modulation. System Type B is primarily covering 16 states
41、 or equivalent modulation. System Type C is primarily covering 64 states or equivalent modulation. “or equivalent“ means providing the same spectral efficiency and system performance regardless of the actual modulation scheme. NOTE 4: For regulatory purposes in national procedures for licensing radi
42、o equipment according to the present document, the above system types shall be identified by the “system type codes“ reported in annex A. NOTE 5: Allocated RF channels may be occupied by systems using any number of sub-carriers or size of sub-carrier bandwidth within a specific channel, as long as t
43、he spectrum mask for the allocated RF channel is not exceeded, for any configuration of sub-carriers. NOTE 6: The CRS transmission, defined as the “downstream“ direction, may be continuous, i.e. TDM (Time Division Multiplex). The CRS may transmit in the downstream direction even if there are no acti
44、ve calls, for the purpose of synchronization of the Terminal Stations. The Terminal Stations (TS) may transmit in timeslots allocated by control signals from the CS, or on a fixed basis. The TS transmission direction is defined as “upstream“. A TS may transmit control, bandwidth requests or signalli
45、ng information even during the absent of users activities. TS transmissions consist of bursts of fixed or variable duration, usually an integer multiple of a fundamental timeslot duration. 4.3 Com pati bi I i ty requirements See EN 301 213-1 i, clause 4.3. 4.4 Envi ron m e n ta I cond i ti ons See E
